6 Claims. (Cl. 121) The invention relates to'a shoe finisher machine and more especially to shoe repairing machinery.

The primary object of the invention is the provision of a machine of this character wherein the working tools of varying types are supported in a turret susceptible of adjustment so that a selected tool can be brought into use in a convenient manner on the adjustment of said turret. 10 Another object of the invention is the provision of a machine of this character wherein the selected tool for use when brought into position for the operation thereof effects passiveness in the other tools as supported by a turret, this being brought about on the adjustment of the turret and in this Way eliminating the necessity for the driving of all of the tools on the turret when it is required that but one be in use.

A further object of the invention is the pro vision of a machine of this character wherein on the bringing of a selected tool into use will serve to automatically render the other tools inactive, that is to say, the tool for use will be in a convenient position for service and those tools remote from the operator of the machine will be out of the way and passive or inactive.

A still further object of the invention is the provision of a machine of this character, wherein footwear can be repaired with dispatch and such footwear finished to have the appearance of a useable for the making of new footwear in that the soles and heels can be trimmed and finishing surfaces thereof had.

A still further object of the invention is the provision of a machine of this character, wherein the construction thereof in its entirety is novel and any desirable tool may be broughtinto position for use with dispatch while the remaining other tools in the set up of the machine will be 40 maintained inactive and in this way saving power in the operation of the machine.

A still further object of the invention is the provision of a machine of this character which is comparatively simple in its construction, throughly reliable and eificacious in operation, easily handled enabling tools to be individually selected with dispatch for service thereof, and inexpensive to manufacture.

50 With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawings, which dis- 55 close the preferred and modified forms of the new shoe or the like, the machine being also embodiment of the invention and pointed out in the claims hereunto appended.

Referring to the drawings" in detail, particu-. larly Figures 1 to 12 inclusive, the machine comprises a stand A including vertically disposed end pieces H3 and II, respectively, these being spacedfrom each other and constitute the legs to the said stand. At the upper portions of these pieces [0 and H are circular bearings 12 and I3 respec- 5' tively. Within the bearing I3 is arranged an eccentric mounting M supporting an electric motor unit l5 being the power unit of the machine. The driving shaft l6 of the motor unit l5 has coupling atll with laidriven shaftl8 55- operating a suction fan is of the bladed type held within a housing or casing 2i) stationarily built with the stand A.

The fan H! of the bladed type is driven directly from the motor unit l5 through the medium of the shaft l8 and this coupling at ll involves a double universal joint setup. Opening into the housing or casing is a cylindrical conduit 2! for collection and delivery of dust or foreign matter to within the said housing or casing on the operation of the said fan, the dust or foreign matter being taken from the work when operated upon by a tool of the machine, these being hereinafter described. This conduit 2! is coupled with a central inlet nipple 2| formed with the housing or casing 25, the conduit 2! bein rotatable and constitutes a part of a turret hereinafter fully described.

The conduit 2! is centered within a tool turret and has .the shaft is longitudinally centered therein, the coupling ll being for the purpose of transferring power from the shaft Hi to the shaft l8 in the operation of the motor unit l5. Turnable about the bearing I 3 and the nipple 2! is the tool turret comprising rotatable end heads 22 and 23, respectively. The head 23 is rotatable on the bearing l3 while the head 22 rotates on the nipple 2|. Concentric to this conduit 2! and journaled in the said heads 22 and 23 are opposed driven shafts 24, these being at opposite sides of said conduit. One of the shafts 24 is furnished with burnishing wheels 25, partially exposed through clearances or mouths in branch leads 26 to the conduit 2i so that when the wheels are active upon work the dust, shavings or removed particles from footwear will be sucked through the branches 25 into the conduit 2! this suction being set up by the fan l3 driven from the motor unit l5. The course of the dust, shavings or removed matter is through the housing or casing 20, the nipple 2i and into the casing 19. Discharge of the contents of the casing I9 is had through a discharge spout 27 for depository in a suitable receiver.

Fitted on the shaft 2i are belt wheels 28 having trained thereover endless belts 29, these being trained over companion pulleys 3B fitted to the driving shaft l5 of the motor unit 15. The shafts 24 are driven from this motor unit. However, on rotation of the turret to bring the tools into convenient position for use, those tools or a tool next to the operator of the machine will become active while those remote will be rendered inactive, This is brought about through the eccentric l4 which slackens these belts common thereto. The pulleys 28, 29 and 30 are confined within the guards or shields 3 I, these being of extensible kind and such as to operate on the belts 29 when slackened so as to cause the latter to leave the clutches of the pulleys 28, 29 and 3D and in this way those tools not to be active will become positively passive. The shields 3! also eliminate the possibility of an operator coming in contact with the driving and driven connections during the operation of the machine. The end heads '23 of the turret at suitable intervals concentric to the conduit 2| are joined together by tie rods 32. The turret is freely rotatable as before set forth.

Carried by the end head 23 of the turret is a bracket 33 having journaled therein spaced parallel rotatable operable stems 34 and 35 respectively, one being for a heel trimming tool and the other for a sole trimming tool hereinafter fully described.

The stems 34 and 35 carry belt pulleys 36 over which are trained endless belts 37. The belt pulleys 36 and the belts 3'! are enclosed in a guard or shield 39 which functions similar to the guards or shields hereinbefore set forth. Each stem 34 or 35 has fixed thereto a circular cutter 48 formed with horizontally arranged radially disposed cutting blades 4l, these being uniformly spaced from each other. The cutter 48 operates within a gauge cap 42 internally threaded for adjustable engagement with an annular rim 43 at the outer open end of a cylinder 44 being telescopically fitted over a tubular base extension 45 which is fixed at 45 to the bracket 33. The stem 34 or 35 is centered within the cylinder 44 and extension 45. The cap 42 is sustained in an adjusted position by a lock nut 48 fitting the cylinder 44 being threaded thereon. The cap 42 has formed therein the arcuate shaped openings 49 and 50 respectively. The opening 49 allows for the introduction of work such as a sole or heel of a shoe or other footwear to the cutter 49 while the opening 50 functions as a dischargeway for trimmings made by the cutter 40. This cap 42 supports an adjustable gauge member 5| being adjustable at 52 for regulating the trimming operation in the use of the sole or heel trimming tool. The sole trimming tool is denoted at 53 while the heel trimming tool is denoted at 54, respectively. The cylinder 44 is adjustable on the tubular extension 45 to regulate the action of the cutter 40 in the operation thereof.

On certain of the shafts 24 is fitted a sanding wheel or disc involving the disc body 55 carrying at its periphery a sanding tape or strip 55, the ends 51 thereof being held fast by clamping rollers 58, these being adjustably fitted within the wheel or disc 55 adjacent to the periphery thereof. Such tape or strip 56 is trained about the periphery of the said body 55 and the rollers 58 clamp the ends of this strip or tape as is clearly shown in Figures 11 and 12 of the drawings. The rollers are held adjustable by friction latches 59 built within the body 55. These rollers 58 are held against lateral displacement by retaining screws 60 engageable in annular channels 6i provided in said rollers. The rollers 58 maintain the tape or strip 56 tight peripherally about the body 55 and such strip or tape is employed for grinding or finishing purposes to the work.

The cylinder 44 is held adjustable upon the extension 45 by a set screw 82 engaged in the said cylinder 44 and binding against the extension 45. By adjustment of the cylinder 44 the cap 42 can be moved toward or away from the cutter 43 with respect to its blades M. This cutter 40 is detachably secured to the stem 34 as at 63 for replacement purposes or for substituting other cutters or new ones.

On the bearing i3 is built a latch 64 which is engageable with the end head 23 next thereto and in this manner the turret is held in its adjusted position to eliminate accidental turning thereof, the turret being manually adjusted and the latch 64 is hand controlled.

Each of the shields- 3! and also the shield 33 involves the outer extensible sections 65 and 83 respectively, these being telescopically fitted so that the same shift with a change of the position of the pulleys 28, 29 and 38 through ec-- centric activity of the turret, these shields being of skeleton form and are provided with side cheeks which fit about the shafts H5, 24, 34 and 35, respectively. I

In Figures 13 to 16 inclusive of the drawings thereis shown a modification of the invention wherein the driving shaft 66 of the motor or power unit is centered with relation to the turret, a portion thereof being indicated at 6! and this shaft 56 carries a plurality of belt pulleys 68 over which are trained the endless belts 69 and 10 respectively. The belt Ill passes over pulleys H fixed to the driven shafts T2 for the sole and heel trimmers hereinbefore described. The belts 69 are trained over pulleys 13 fixed to the shafts i l journaled in the turret 6'! concentric to the driving shaft hi5 which is the axis for the said turret.

Fitting the tie rods 15 for the turret 61 are rocking belt tighteners l6 and Ti respectively all being fitted with belt engaging rollers 18 for contact with the companion belts 69 and H3. The power unit 79 which is stationary and is located centrally with relation to the end head of the turret 6'! has built exteriorly thereon a cam Si which operates upon adjustable heel screws 82 fitting the belt tighteners 16 so that a determined tightener will be operated upon by the cam 8! to tighten the belt common to this tightener so that such belt will be effective for operating a selected tool supported by the turret 61 while the other belts for operating the other tools on the turret will remain slackened and those tools rendered inactive. By adjustment of the screws 82 the tightening effect of the .belt tightener it can be regulated and in Figure 14 of the drawings one of the belt tighteners is in position for the tightening of one of the belts While the remaining belt tighteners are inactive against the other belts so that but one tool of the turret will operate while the other tools of said turret remain passive or inactive.

The arrangement and set up of the belt tighteners operates for the same purpose as does the eccentric l4 yet it is not required that the turret 8? have eccentric access with respect to the driving shaft 66 of the power unit 19 as is required in the use of the eccentric I l hereinbefore set forth.

It is of course understood that the structure herein described and illustrated in the drawings constituting the present invention is applicable to other types of machinery where it is desired to have one or several shafts active through selectivity and other shafts in the set up rendered inactive, therefore the present invention is not to be construed as restricted to the specific type of machine hereinbefore described.
